Over the course of his career,
Jelly Jackson
made 1,224 plate appearances.
Jackson
was worth
-3.8 Wins Above Replacement
and -7.5 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the -3.8 WAR becomes
-8.9 adjWAR. Then, WAA is adjusted by ignoring negative seasons
(thus, truly capturing a player’s peak seasons) and making similar adjustments for catchers and relief pitchers.
After these adjustments, the -7.5 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Jackson -8.9 wWAR. wWAR is then converted to Hall Rating.
A Hall Rating of 100 represents the Hall of Stats borderline (similar to OPS+ or wRC+, where 100 represents league average).
Jelly Jackson has a Hall Rating of
-8,
leaving him nowhere close to induction to the Hall of Stats.
